During a sale, markers cost $4.00 each. For every 4 markers purchased, the customers received 2 free. If 80 markers were given free and the sales totaled $840.00, how many individual markers were purchased?

(No one purchased more than 4 markers.)


This question was in my son's homework. Can you solve it without external assistance?

You should just ask a few posters to volunteer to answer this. May I suggest InHindsight, Nicoutr, BeatDballs, de WICricketfan?

lollollol

De only problem is that all a dem jokers will need help.

Is shoplifting factored in?

That's a very very tricky question. It took me a good 1/2 hour to grasp what they were asking!

A quick scratch of paper gave 50 individual markers?

There are 2 free for every group of 4 purchased which totaled 80 'free' => 80/2 = 40 sets of 4 were purchased

so individual # of groups of 4 => 4 x 40 = 160 markers purchased as groups of 4

Therefore, $4*160 + $4*M1 = $840 where M1 is number sold as individual markers

solve for M1 => 4M1 = 840 -640

4M1 = 200

M1 = 50

Is my logic wrong?

There is some serious ambiguity in the question.

It is a ridiculous problem.

I suspect the questioner intended to ask: How many markers were removed from the inventory/stock?

Its not how many markers were sold in total.

ITs how many INDIVIDUAL markers!!

That's the trick they threw in!

It's definitive that what is given away free is not purchsed individually.


Tthe ratio of markers sold: to given free is 2:1

that's right, so they're asking for how many individual markers were purchased.

Can you tell me the number of markers which left the stock?

My limited elementary education tells me since 80 were free, 160 were sold. 160 X 4 =640 = 40 sets of 4. Since $840 were the total sales.
Individual sales will amount to 840-640 = 200/4$ ea =50

It’s a very tricky question indeed.

OK, if you sales = $840.

Each marker cost 4 dollars

We cannot determine the number of markers sold...$4.00 is the cost price...selling price ?????

What is the total number of idividual markers sold??

All markers purchased were individually sold.

I will sign up for some lessons, my ole hard head and all.

But seriously, not sure how old the poster's son is, but I ask what purpose is an education system trying to gain by posing a question like this in a general class. In today world the skill set needed to succeed in life is vastly different.

I can understand a specific math class for those gifted math students majoring in maths- those who may be mathematicians.

Every student who gives an answer to this question should receive full marks...it is such an ambiguous question.

Most age 11 cohort of students awill likely answer this way considering that at age 11 kids will not answer this algebriacally:

If 80 makers are given free:
Total number of markers in transation = 160 supposedly sold @ $4.00 (simple 2:1 aliquot) + 80 (free giveaway) =240;
Eack individual would purchase a 6 pack=240/6 = 40.

...........................................
Therefore cost per marker = 840/240 = $3.50
Total number of package of 6 pack sold = 840/3.5 = 240 (50 cents discount per marker).

Cheeks and Stump cam got it right.

I prefer Stumpcam's working as its more in line with what they teach at primary school!!

But Cheeks figured it out in minutes!!

So lemme ask you how many individuals bought a six pack?

Please, please answer?

80 makers given free.

In a 2:1 ratio 160 sold

Total = 160 + 80 = 240

240 divided by 6 = ?????

the question says :
(No one purchased more than 4 markers.)



Stumpcam and Cheeks explained the approach properly.

2:1 aliquot of 240 (free)=80
2:1 aliquot of 240 purchased = 160.

Total package = 240

Each individual purchases a six pack

How much individuals will purchase 240?

They purchased the minimum of 4 individual markers to get 2 free.

All markers were sold singly.

...For every 4 individual markers purchased, the customers received 2 free...


Each customer who purchased 4 left with a six pack but the four markers were not sold as a group.

160 units sold (40 packets of 4) + 80 free = 240 individual markers were purchased and taken out of inventory.

In the real world your sales in accounts will reflect 240 markers sold @ $3.50 per marker (forget the cost of the marker).

Simple sales gimmick...don't be fucked by an 11 year-old kitten.
